UV-CURING PROCESS WITH EXTERIOR MASKING FOR INTERNAL AND SELECTIVE DECORATION OF TUBE-LIKE AND 3D ELECTRONIC HOUSING

摘要

An aspect of the present disclosure provides a method of selectively coating an internal surface of a tube-like wall. The tube-like wall may have an internal surface, an external surface, and a hollow interior defined by the internal surface. The method may comprise steps of coating at least a portion of the internal surface of the tube-like wall with a coating material that is selectively curable by exposure to initiation energy; and selectively transmitting initiation energy from outside the tube-like wall, through the tube-like wall, into contact with a portion of the coating material, under conditions effective to cure the contacted portion of the coating material, and at least substantially without curing another portion of the coating material unexposed or less-exposed to the initiation energy.

1. A method of selectively coating an internal surface of a tube-like wall, the tube-like wall having an internal surface, an external surface, and a hollow interior defined by the internal surface, the method comprising:
coating at least a portion of the internal surface of the tube-like wall with a coating material that is selectively curable by exposure to initiation energy; and selectively transmitting initiation energy from outside the tube-like wall, through the tube-like wall, into contact with a portion of the coating material, under conditions effective to cure the contacted portion of the coating material, and at least substantially without curing another portion of the coating material unexposed or less-exposed to the initiation energy.
